According to the CEO of GoFundMe, Rob Solomon, medical fundraisers now account for one-third of fundraising campaigns hosted by the crowdfunding website. This tactic is increasingly used by patients to defray the cost of expensive medical bills. Sara Collins, an economist at the Commonwealth Fund, claims that these exorbitant costs are partially due to high deductibles and copays. She emphasizes that being underinsured can be just as costly as being uninsured.
